Double protection guides different view angle (photo of functional machine) |
|
Lubrication grooves |
The grease collection barrier are installed in the both sides: 4 barriers in total. Grease flow interconnects with the grease collection tank
|
|
Motor head Lifting |
High precision ball screw is installed. The screw is long enough to feed below the magnet surface of about 11-20 mm and high enough to easily replace the grinding segments without removing the grinding head. As shown on the pictures on the right.
Also, the max up and down moving positions are limited by the highest and lowest point electronic switchers.
